This patchset adds the PCIe L1 PM substate support to the kernel. The feature is described at: https://pcisig.com/sites/default/files/specification_documents/ECN_L1_PM_Substates_with_CLKREQ_31_May_2013_Rev10a.pdf
Its all logically one patch (and may be some of them should be squashed later) , but I've broken down into smaller patches for ease of review.
This is currently rebased on top of Bjorn's master branch.
Rajat Jain (6): PCI: Add L1 substate capability structure register definitions PCI/ASPM: Introduce L1 substates and a Kconfig for it PCI/ASPM: Read and setup L1 substate capabilities PCI/ASPM: Calculate and save the L1.2 timing parameters PCI/ASPM: Actually configure the L1 substate settings to the device PCI/ASPM: Add comment about L1 substate latency
